Problems solved by technology

[0003] However, at present, there are many difficulties in processing the valve seat cone surface and the cylinder head conduit hole: the conduit hole has a large aspect ratio and the product structure is very compact. very difficult
In order to improve the processing quality and production efficiency, special machines and special machine automatic line processing, multi-tool processing or compound tool processing are often used, but the existing tools cannot meet the requirements of processing and production for products.

Embodiment Construction

[0023] Such as figure 1 , figure 2 , image 3 with Figure 4 The compound tool shown for processing the valve seat cone surface and the cylinder head conduit hole includes a tool handle 1, a reamer 2 and a blade 3, and the reamer 2 passes through two symmetrically arranged locking jackscrews 10 on the tool handle 1 Locked in the handle 1, four symmetrically arranged adjusting jackscrews 11 at the front end of the handle 1 are in contact with the reamer 2 to adjust the beating degree of the reamer 2 by means of a knife adjuster. The blade 3 is movable and pressed on the conical surface of the knife handle 1 through the pressure plate 7 and the pressure plate screw 13 on the cone surface of the knife handle 1. The head and tail of the blade 3 are respectively provided with a limit pin 8 and an adjustment pin 9. The limit pin 8 The blade 3 head is positioned, and the adjustment pin 9 is used to adjust and change the inclination angle of the blade 3 cutter head, and the cutter...

Abstract

The invention discloses a compound tool for processing the guide pipe hole of a cylinder cover and the conical surface of a valve seat. The compound tool comprises a tool handle, a reamer, and a blade; a reamer clamping mechanism is movably clamped in the tool handle; and the blade is movably arranged on the conical surface of the tool handle through a compressing mechanism. The compound tool is a split compound tool; the reamer and the blade can be replaced unlimitedly, the disadvantages brought by unbalanced service lifer of the reamer and the blade are avoided, the tool handle is recycled, the raw materials are saved and processing cost is reduced, and simultaneously, the processing quality and the production efficiency are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of machining equipment, and in particular relates to a composite tool used for machining cylinder head conduit holes and valve seat taper surfaces. Background technique [0002] The positional relationship between the conduit hole of the cylinder head of an automobile engine and the cone surface of the valve seat is as follows: the valve reciprocates in the conduit hole, and at the same time, the valve head must ensure a good fit with the cone surface of the valve seat. The matching quality of the intake and exhaust valves of the automobile engine and the cone surface of the cylinder head valve seat, the position and coaxiality of the sealing cone surface of the seat ring relative to the conduit hole of the cylinder head directly affect the output power, fuel consumption, leakage rate, etc. of the automobile engine . Therefore, when processing the cylinder head of an automobile engine, the taper surface of ...
